To avoid dispersion of the accruing sedimentation layer, the inflow into the cistern should be done through an inlet calmer.

 According to the European Drinking Water Directive <ref name="Europäische Trinkwasserverordnung">European Drinking Water Directive</ref> water in households, which is not used for drinking or bodily hygiene, can be replaced with so-called non-potable water. This non-potable water can be relatively easily collected from roof runoff water. Roof runoff is rainwater that has come from roof surfaces. At minimum non-potable water can be used for toilet flushing, laundry washing or for irrigation purposes. In this way a savings-conscious household can save up to 50 L of drinking water per person every day. Considering the usage in Germany, this constitutes around 50% of the total usage.

 The rainwater yield depends on the size and type of the connected roof surfaces and the precipitation amount. If possible, all existing sealed surfaces and roof areas should be connected to achieve the highest possible yield. Different types of roofing materials differ in both their flow characteristics as well as in the potential contamination of the gathered water gathered.
